Masterflex Ultrapharm™ L/S® Pump Heads, Avantor®

Every drop counts—integrate into automated filling systems for high accuracy dosing and dispensing.

• Offset rollers and planetary gearing ensure dosing accuracy (±0.5%), low pulsation, and long tubing life
• Masterflex double-Y tube sets ensure proper retention, repeatability, and accuracy
• 250 rpm max speed; dosing volumes from <0.5 ml to >500 mL
• Easy on tubing—planetary drive rollers reduce drag on tubing for longer tubing life and reduced risk of premature tubing failure
• Whisper quiet operation reduces extra noise on the floor or in the lab
• Autoclavable pump head; tested to 10 cycles without any loss of flow or accuracy performance
• Pump head is available in either an aluminum body version or a 316 stainless steel body version; choose stainless steel for bioprocess and cleanroom applications

The Masterflex Ultrapharm™ L/S® Pump Head, part of the Masterflex® line of products, is designed to be used in the fill/finish step. This pump head produces gentle, low pulse, and highly accurate dosing and flow to ensure optimal integrity and uniformity. Designed with offset rollers, the pump head provides linear flow throughout the flow range. While one roller is drawing fluid through one leg of the double-Y tube set, the other roller is pushing fluid through the other leg. Also, dual channels allow for a lower rpm in order to achieve “single-channel” flow rates. A lower rpm means reduced shear forces to maintain fluid and molecular integrity.
